Car shaking between 40-60 mph!! help!!!

[95MustangV6]

I have been having this consistent shaking in my car when i travel anywhere from 40-60 mph. I have had all my tires balanced and had a front end allighnment.

I can feel the vibration in my seat, steering wheel, and occasionally the stick. (5-speed.)

Any thoughts or ideas where to check would be greatly apreciated.\
Thanks.

U joint. Check ur driveshaft.

might also be balljoints or tie rod ends.

unbalanced driveshaft, unbalanced tires, bad u joints.

I would look at those first.

even if you had an alignment youre geometry may be off. human errors.

yup, the old shop that aligned my car after I got coilovers and the MM 4 bolt c/c plates said my car was "not alignable to my specs". They were just retarded. lol

Could be badly warped rotors maybe I know my rotors are warped and when I get on the brake slightly at those speeds I feel the pulsation in my steering wheel.

If you put one of the front tires up on a jack, you can grab ahold of it 3 o'clock and at 9 o'clock and check for any play back and forth. I would bet that taking it to a shop/dealer that uses the "HUNTER Road Force Balancer" will straighten things out. The machine balances each wheel with a load roller that applies thousand pounds of force against the tire while balancing it. This machine can help compensate flaws in the tire or wheel.
